GFB WGA Internal Wastegate Actuator Mitsubishi Lancer Ralliart (CY4A)

GFB WGA Internal Wastegate Actuator - Mitsubishi Lancer Ralliart (CY4A)

GFB's WGA is a high performance internal wastegate actuator engineered to solve the boost control limitations of the factory unit. Using an industry-first Nomex-reinforced silicone diaphragm and a PEEK pivoting rod guide, it delivers stronger control authority over the wastegate flap for faster spool up, less high RPM taper, and a more stable boost curve on the Mitsubishi Lancer Ralliart.

This listing covers the Mitsubishi Lancer Ralliart (CY4A), 2007-2017, fitted with the factory turbocharger. SKU 7300 bolts directly to the OEM wastegate actuator location.

Important: This is a tuning tool that will increase boost pressure beyond factory levels. Retuning is required after installation.
